GUIDE FOR PIANOLAS.

SPECIFICATION forming part of Letters Patent No. 630,558, dated August 8, 1899.

Application filed February t, 1899. Serial No. 704,506. (No model.)

T0 at whom it IN/(Ly concern.-

Be itknown that I, ROBERT W. PAIN, a citizen of the United States, residing in the city of New York, borough of hflanhattan, county and State of New York, have -invented a certain new and useful Guide for Pianolas, of which the following is a specification.

My invention relates to a guide for positioning an automatic playing device known as a pianola belonging to a piano and for preventing relative movement between the two when the pianola is in operation.

I will describe a guide embodying my invention and then point out the novel features thereof in the claims.

In the accompanying drawings, Figure 1 is a top View of a piano and a pianola in playing position before the piano and of guides embodying my invention. Fig. 2 is an enlarged top view of a guide embodyingmy invention. Figs. 3 and 4: are each detail views of: parts of the guide.

Similar letters of reference refer to corresponding parts throughout the several figures.

A represents a keyboard of a piano, and B a device, such as a pianola, for automatically operating the keys of the piano. The device B is separate from the piano, and when not in use it may be moved away from it. In bringing the pianola in position before the keyboard it is necessary that the playingfingers of the pianola be accurately placed over the proper keys and the pianola held in this position while it is being operated. This may be done by means of guides O G, placed at each end of the pianola, one part of each guide being secured to the piano-casing and the other part to the pianola. Each guide is made up of two parts 0 c. The part 0 cornprises an attaching-piece 0 provided with slots 0 which permit of its adjustment, and an arm 0, that is hinged at one end to the attaching-piece 0 The arm 0 is provided with an adjusting-screw 0 against which the second part c of the guide bears. This screw is for the purpose of holding the pianola away from the keyboard, so that its fingers will be in proper position over thekeys. The arm 0 is also provided with a curved surface 0,

which serves to guide the part 0 into engagement with the adj [lS'tlDg-SGI'OW. The part c is seen red to the under side of the keyboardbed. The part c of the guide is preferably secured to the pianola and comprises an attaching-plate c and a head 0 which engages with the screw 0 Then the pianola is not in use, the arms 0 of the guides are turned inward under the key-bed of the piano, as shownin dotted lines, Fig. 2, so as to be out of the way.

What I claim as my invention is- 1. A guide for positioning an automatic playing device before the keys of a piano comprising two parts, one of which is secured to the piano so as to be adjustable thereon longitudinally of the keyboard, and the other of which is secured to the automatic playing device and is adapted to bear against the part carried by the piano.

2. A guide for positioning an automatic playing device before the keys of a piano,comprising two parts: one of said parts consisting of an attachingbase, an arm hinged to said base, and the other of said parts consisting of a piece which bears against the said arm.

3. A guide for positioning an automatic playing device before the keys of a piano com prising two parts; one of said parts consisting of an attaching-base, an arm hinged to said base, and the other part consisting of an attaching-piece and a head which engages with said arm.

at. A guide for positioning an automatic playing device before the keys of a piano,comprising two parts, one of said parts consisting of an attaching-base,an arm hinged thereto, and an adjustable screw which is carried by said arm, and the other part consisting of an attaching-piece and a head which engages said screw.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ROBERT W. PAIN.
